DGPS SURVEY : Differential GPS (DGPS) surveys use a network of fixed ground-based reference stations to enhance the accuracy of standard GPS by correcting signal errors. This technique provides highly precise positioning data, essential for tasks like mapping, navigation, and geodetic measurements. TOTAL STATION SURVEY : Total station surveys utilize laser machines to accurately measure angles and distances, combining electronic distance measurement (EDM) and angular measurements for precise data collection. These laser-enabled instruments enhance efficiency and accuracy in land surveying, construction, and engineering projects. AUTO LEVEL SURVEY : Auto level surveys use an automatic leveling instrument to establish or verify points in the same horizontal plane, ensuring precise elevation measurements. This method is essential for construction projects, topographic mapping, and engineering applications, providing accurate and reliable data on land elevation.

Various instruments are utilized across different types of land surveys to ensure precision and accuracy. For topographic surveys, instruments like total stations, GPS receivers, and digital levels are commonly used to measure elevations and map contours. Construction surveys rely on total stations, theodolites, and laser levels to mark and verify construction site features. Subdivision surveys often use total stations and GPS systems to divide land into smaller parcels accurately. Site planning surveys combine tools like total stations, GPS receivers, and sometimes drone technology for comprehensive site analysis. ALTA/NSPS Land Title surveys require precision tools such as total stations and GPS equipment to meet stringent standards for commercial properties. Hydrographic surveys use sonar systems, echo sounders, and GPS for mapping underwater features. Geodetic surveys involve high-precision instruments like geodetic GPS receivers, theodolites, and sometimes satellite technology to measure large areas and establish control points. As-built surveys typically use total stations, 3D laser scanners, and GPS to verify that construction work matches design specifications
